Ta a/ZZ whom/t may concern.-

Beit known that we, EDWARD B. HEss, ofthe Machines, of which thefollowing is a specification.

to lThis invention relates to devices for feeding, guiding,controlling,and delivering paper sheets, cards, or envelops ordinarily used inwriting-machines to the platen and coacting parts. Its purpose is tocontrol the paper accurately and efficiently at all stages of itspassage to and around theplaten and to provide for the ready andaccurate use of mul-y dially of the platen to permit the passage betiplesheets of paper or cards.

As will be hereinafter apparent, the invenzo tion is applicable tovarious styles of machines, even to understroke machines, withoutsubstantial modification in the principles of construction and mode ofoperation. It has, however, been shown as applied to a front-strokeor-visible-writing machine.

We employ an `endless-band paper-feeder so arranged that it will travelin contact with the surface of the cylindrical rotatable platen at aside of the platen where the printing 3o does not occur. It ispreferably a unitary band or structnreand is of such width as to contactor coperate with both the central and end portions of the platen and ispreferably of'a width equal or substantially equal tothe greatest widthof sheet the machine is adapted to receive. Cards or envelops or widesheets may, therefore, be fed without adjustment or change of any kindand willbe eiliciently held and fed or directed around the 4o platen. Itmay be feasible to divide such an endless carrier longitudinally intotwo or more parts and yet have them behave in the desired manner. It isbelieved, ho\vever,\that the best results are obtainable when thecarrier is continuous transversely. Such a carrier should be ofnonelastic material to obtain the best results, although the materialmay, perhaps, be more or less elastic and the carrier operatesatisfactorily under proper 5o conditions. In Iorder to insure a certainand platen. `mounted and arranged with reference to the platen that whenno paper is being fed the carrier bears upon the surface of the platenuniform feed, particularly where multiple sheets are fed to the machine,we provide that the endless carrier shall be driven positively, and itis best that when so driven it should have the same surface speed as theSuch an endless carrier being so and the platen and carrier both beingpo'si- 6o tively driven at the same surface speed dur- .ing thefeedingroperation, it follows that 'the sheet or sheets inserted betweenthem will he carried around the platen with accuracy and with a minimumdisturbance of the relation of the sheets where multiple sheets are fed.The carrier should be capable of yielding ratween the two members ofmultiple sheets of such thickness as may be desired, and 'it is 7o verymuch preferred that this capacity of the carrier should depend upon theparts upon which it run-s and not upon its own elasticity.

An organization such as suggested comprising an endless-band carrier ofnon-elastic material and positively driven to run inthe same directionas the surface of the platen at the same surface speed and incontacttherewith involves a principle which, so far as is known, isentirely novel in this art. 8o

While, as stated, the best results are obtainable by employing a unitaryendless carrier of such width as to contact and coperate at the sametime with the central and end or lateral .portions of the platen, someof the advantages of this invention maybe obtained by employing feeddevices comprising two or more narrow endless bands arranged withreference to the platen as in the Well-known Remington understrokemachine or asshown 9o in the patent ofSpiro, No. 463,464, making thebands, however, of non-elastic material and driving them positivelyat`.the same surface speed as that of the platen.

In connection with an endless carrier of the character indicatedguidesor delivery members are employed which, in coaction with the platen,receive. the cards or sheets from the endless carrier and while properlyholding them during the act of printing deliver roo them from theplaten. These guides or delivery devices preferably consist of endlessbands, which, as herein shown, are frictionally driven from the platen,and they are so mounted and disposed as to be capable of adproperlyguide the greatest 'thickness of sheets or cards that maybe delivered tothem by l the endless carrier. If they are endless bands, they may beelastic or non-elastic, and in the latter event their radial movementcould be derived from the parts on which they are mounted.

So far as is known endless-band guides cooperating with that side orface of the platen where the printing occurs and adjustablelongitudinally of the platen are new. Preferably in conjunction withthem the endlessband feeder or carrier coacting with the olf surface orside of the platen is employed, the conjoint use of these twoorganizations giving in a writing-machine ideal conditions and aninexpensive and simple construction.

In the machine herein illustrated and specifically described the feedingdevices or endless carrier are located in rear (having reference to theline of travel of the paper) of the printing-line, and hence may coactwith any portion of the platen. The subsidiary devices, which have beentermed guides, and which may also be endless bands, and which receivethe sheet from the carrier or feed devices, may lie wholly beyond theprintingline oracross-t'- e., on both sides of-the print ing-line. Thesedevices, coacting, as they should, with the printing-face of the platen,should be adjustable longitudinally of the platen to adapt them tosheets or cards of different width.

In the accompanying drawings, Figure lis a plan View, partly brokenaway, transversely through the central portion; Fig. 2, a frontelevation; Fig. 3, an elevation of the righthand end of the machine withthe carriagecarryingrails in section; Fig. L1, asimilarview of theleft-hand end of the machine; Fig. 5, a detail view indicating theroller-bearing of the carriage upon the carrying-rails; Fig. 6, a detailtransverse section showing only the platen, endless carrier, guides, andassociated parts; Fig. 7, a like view showing the same parts in adifferent position; Fig. 8, a detail View showing one of thechannel-arms in which the lower rolls of the endless guides are mounted;Fig. 9, a front elevation, and Fig. 10 a transverse section merelyindicating an organization in which in lieu of endless-band guidesordinary clamping-fingers are employed.

The carriage is composed ot' end plates a a, tied together by bars. Thecarriage-rails b l) are to be supported in any appropriate way in theframe of the machine. They are located, respectively, at the lower frontand rear top parts of the carriage and are formed with longitudinalgrooves, preferably V- shaped, in which run antifriction-balls c, spacedby a perforated plate d, Fig. 5, and embraced above by correspondinggrooved rails or bars c e, forming part of the carriage. This structureaffords a practical and very efficient mode of mounting the carriage. Ithas been deemed unnecessary to indicate a frame and carriage actuatingdevices. They, as well as the type-bar and other usual mechanism of awriting-machine, may, except as herein stated, be of any suitablecharacter.

The platen f, of any usual character, has upon its shaft the usualhand-wheel. At one side of the platento the rear, as here illustrated-ismounted a pulley g, turning in bearings in the end plates a a andsubstantially equal in length to the platen. Around this elongatedpulley or roller passes an endless band h, as wide, substantially, asthe platen is long. Below the platen and somewhat in front of a verticalplane passing,r through its axis is a roller or pulley fi, preferably ofsomewhat less diameter than g, but of equal length. The pulley t' issupported in bearings in arms 7c, preferably curved somewhat to conformto the curve of the platen and pivoted in rear of the platen adjacentthe ends of the roll g in brackets m, mounted on the end plates of theframe. The arms have projections extending upwardly and forwardly in thespecial construction shown from their pivots and have pivoted to theirends links n, which incline upwardly and somewhat rearwardly and arepivoted at their upper ends in the lower ends of downwardly andrearwardly extending radial arms o, attached to a rock-shaftp, mountedin bearings in the end plates.

In the normal position of the parts thus far described and as shown inFigs. 3 and 6 the endless-band carrier h bears upon the under face ofthe platen and being, as shown, substantially as wide as the platen islong makes contact with it centrally as well as at or adjacent its ends.Sheets of paper, cards, or envelops introduced between the platen andthe endless carrier will take the direction indicated by the arrow inFig. 6 and passing loetween these two members will be carried aroundunder the platen. A spring 50, to be applied, as shown in Figs. G and 7,to each arm 7c or otherwise, serves to draw the endless carrier againstthe face of the platen, but permits of its being forced away therefromto accommodate different thicknesses of paper or cards introducedbetween them. Obviously if the rock-shaft p be turned in the IOO IIO

ro` figures of the drawings.

Of course it is to be understood that the invention is not limited tothe precise manner of mounting and operating either the endless-g bandcarrier or the endless-band guides.

Figsl, 2, and 4 show line-space devices operated by a hand-lever 11.They are of ordinary construction and form no part of this invention.

The common device of crowning the rolls zo or pulleys'upon which thebands `run to cause them to travel accurately may be employed in 'thisconstruction. The crowning, however, will be very slight, so as not todisturb, practically, the parallelism of the different,

z parts of the bands or their uniform coactionl at all points with thesurface of the plateni This crowning of the rolls would be so slight;that it would not be perceptible in the draw ings, and as it is a commonexpedient it haS 3o been thought not desirableto exaggerate thevdrawings to illustrate it. j vIn the construction illustrated theprinting line or point may be at 12, Fig. 3.

The term cylindrical platen used in the 3 5 claims includes ordinaryforms of rotary platens usable in writing-machines and which may bedescribed generally as cylindrical,and does not require that theperiphery of the platen shall be a perfect circle.

In this specilication and in the claims the endless-band carrier hasbeen described as positively driven. By this term is meant a definitedriving of the endless carrierregardless of its frictional contact withthe platen.

In the drawings the carrier is so shown as definitely or positivelydriven by reason of its bite or hold upon its positively-driven roll. Asstated in this specification, however, the same result may be producedin other 5o ways.

IVe claim as our invention- -f 1. In a writing-machine, the combinationwith a rotatable cylindrical platen, of an endless unitary band carrieradapted to travel at 5 5 the same time in contact with the central andside portions of the cylindrical surface.

3. In a writing-machine, the combination with a rotatable cylindricalplaten', of an endless unitary band carrier adapted to travel at thesame time in contact with the central and carried around the platentoward the printf ing-point bythe conjoint action of the surfaces of theplaten and carrier betweefi' which the sheets travel. p u

5. In a'writing-machine, the combination with a rotatable cylindricalplaten, of an endless-band carrier running in contact with the centraland side portions of the cylindrical surface and positively driven'atthe same surface speed.

6. In a writing-machine, the combination with acylindricai rotatableplaten, of a unitary endless band carrier arranged centrally of theplaten and adaptedto run in contact therewith, and means-for drivingVthe 'carrier at the same surface speed as that of the platen.

7. In a writing-machine, the combination with a cylindrical rotatableplaten, of a unitary endless band carrier of a'width approximately equalto the length of the printingsurfaceof the platen and adapted to run incontact therewith, and means for driving the carrier at the same surfacespeed as that of the platen.

'v

9. In a writing-machine, the combination with a rotatable cylindricalplaten, of an end- IOO IIO

less-band carrier running in contact therewith and positively driven atthe same surface speed, and means for throwing the carplaten and carrierbetween which the sheets travel. s

l1. In a writing-machine, the combination with a rotatable cylindricalplaten, of a posil `tively-driven endless-band carrier travelingdirection of the hands of a watch, as viewed in Fig. G, the effect willbe for the radial arm o and link n to throw the arm downwardly and movethe endless carrier out of contact with the face of the platen or topermit it to become so slack as to allow of the adjustment by theoperator of a sheet or sheets already in the machine. The large surfaceof contact of the endless carrier with the introduced sheets or cardscarries them readily around under the platen as the platen is revolvedand,

incidentally-by friction, it may be-the contiguous surface of thecarrier is caused to travel at the same speed as the paper. As shown inFig. 7, when the shaft p is rocked through a sufficient arc the toggleaction of the arm o and link n will hold the carrier away from theplaten. The rocking of this shaft may be conveniently accomplished bymeans of a projecting hand-lever q, keyed thereto.

A further important feature of this invention is the positive driving ofthe endless-band carrier at the same surface speed that the platen has.This may be conveniently done by means of a gear-wheel 1^, placed at oneend of the platen and meshing with a pinion s on the shaft of the pulleyg, Figs. l and 3. Experience has demonstrated that with an organizationof this kind cards or sheets of paper forming a pile or collection ofvery considerable thickness may be introduced and carried around theplaten without disturbance of their relative arrangement with quite thesame facility that a single sheet or card may be handled. Aside from theadvantages of operation, the structure is one of small cost, and theusual paper-table, along or over which sheets are fed to the machine,may be dispensed with. While the endless band at all points of contactwith the platen presses the intervening sheets against the platen, thisis particularly so at the forward roll t', which is or may bedistinctively a pressure-roll.

As shown in the main figures of the drawings, front guides or bands arearranged just above the roll t' or forward portion of the endlesscarrier. These guides may be of appropriate width, but are relativelynarrow, and are so mounted and arranged as to be respectivelyindependently adjustable longitudinally of the platen and capable ofbeing moved away from the surface of the platen. As shown in Fig. 6,these guides or bands t when in normal position press against andconform to the surface of the platen and are driven frictionally. Whenthrown outwardly for the adjustment of a sheet, they may pass entirelyout of contact with the platen, if desired, or bear lightly thereon, asshown in Fig. 7. Each band passes around a roller u,

suitably adjacent the rollerz'and having bearings in the lower end ofthe curved arm c, preferably of channel-iron to afford sufficientrigidity, turning at its upper end upon a bolt w, projecting laterallyfrom a horizontal arm :r and having upon its end a pulley y, aroundwhich the band also passes. The horizontal arms r extend part way acrossthe top of the platen and each forms part of a block z, movable upon asquare or angular' bar 1, extending between the end plates of the frameand upon which the blocks are capable of being adjusted longitudinallyby means of setscrews, as shown. The rock-shaft p, before mentioned,passes through apertures in th armsac and in lugs 2, also forming partof the blocks e and arranged, respectively, adjacent the arms 0c. Fromthe shaft p between the parts a"l and 2 project upwardly arms 3, movablelongitudinally on the shaft by means of slot-and-key connection and towhich are pivotally connected the rear ends of links 4, whose front endsare slotted to embrace apin 5, fixed in the aperture 6, Fig. 8, of thepart 7 of channel-iron fu, extending upwardly beyond its pivot-bolt w.When the rock-shaft is actuated by the hand-lever q, as alreadydescribed, or otherwise the first action that is commenced is theswinging of the endless carrier h away from the platen, following whichthe pin 5 comes against the end wall of the slot in the link Il and thechannel-iron arms u are swung upon their pivot-bolts w to throw the bandcarriers t away from the platen. The band carriers are normally pressedagainst the face of the platen by the springs 50, applied tothe arms 7a.When the parts are thrown into position shown in Fig. 7, the band guidest, as well as the endless carrier h, are maintained in their outwardposition by the toggle action between the parts -n o.

The rear roll of the endless carrier or that at the entry side of theplaten need not be movable toward and from the platen, while the frontroll may be. The latter in the construction shown acts as apressure-roll, and between the two the endless feeder or carrier has arelatively long surface contact with the platen, and for that reason itis not necessary that there should be any great pressure between theplaten and carrier. With ordinary feed-rollers contacting with theplaten at single points only relatively greater pressure is required toenable the machine to perform the ordinary operations expected of it.Such reduction of pressure, possible with the present organization, hasa beneficial eect on the action of the retaining-pawl acting on theplaten ratchet-wheel, permitting more accurate seating of the pawl withless spring-pressure.

The guide-band rolls adjacent the roll of the carrier and which, asshown, are pressure-rolls may be movable; but the other guide-rolls neednot be, and the latter being placed a suitable distancey from the faceof the platen act, with the aid of the bands, to deliver the printedsheets or cards from the platen.
